Perforation rates after ventilation tube insertion: does the positioning of the tube matter?
1ENT Department, Royal Victoria Hospital, Belfast, Northern Ireland.
Insights
This study on ventilation tubes for glue ear in children found a 4.6% perforation rate. Posterior tube placement showed a slightly higher perforation risk than anterior placement, though not statistically significant.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Audiology
Background:
- Secretory otitis media (glue ear) is common in children.
- Ventilation tube insertion is a standard surgical treatment.
- Understanding potential complications like tympanic membrane perforation is crucial.
Purpose of the Study:
- To compare the rate of tympanic membrane perforations between anterior and posterior ventilation tube insertions in children with glue ear.
- To evaluate the safety and efficacy of different ventilation tube placement techniques.
Main Methods:
- Prospective study of 121 children (9 months to 10 years) undergoing bilateral ventilation tube insertion for glue ear.
- Each child received one anterior and one posterior tube in different ears.
- Clinical and audiological assessments were conducted until tube extrusion.
Main Results:
- Overall tympanic membrane perforation rate was 2.75% (4.6% of children).
- Posterior tube placement had a perforation rate of 3.7% compared to 1.8% for anterior placement.
- The difference in perforation rates between anterior and posterior placements was not statistically significant.
Conclusions:
- Bilateral ventilation tube insertion for glue ear is associated with a low rate of tympanic membrane perforation.
- While posterior placement showed a numerically higher perforation rate, current evidence does not strongly favor one placement over the other based on this study's findings.
Abstract:
A prospective study was performed of children undergoing bilateral ventilation tube insertion. One hundred and twenty-one children aged between 9 months and 10 years 3 months were admitted for surgery for secretory otitis media (glue ear). Each child had a ventilation tube inserted anteriorly in the tympanic membrane of one ear and posteriorly in the tympanic membrane of the other. They underwent regular clinical and audiological assessment until extrusion of the ventilation tubes occurred. Perforations were noted in 2.75% of tympanic membranes (4.6% of the children). The rate with posteriorly placed ventilation tubes was higher than with the anteriorly placed ventilation tubes (3.7% compared with 1.8%) though this is not statistically significant.
